Label Info: when you put this in your product, your label needs to read Hydroxypropyltrimonium Lemon Protein, not Quaternized Lemon Shine. Quaternized Lemon Shine is a product name, not a legal INCI name.
Quaternized Lemon Shine is a naturally derived protein designed to help with Hair Conditioning, Enhances Hair Shine, Decreases Fizz. Designed to be used in natural hair care products at 0.5-5%, this ingredient is an easy addition to any of your hair care formulas.
Quaternized Lemon Shine consists of lemon protein that is hydrolyzed to decrease pH and solubility reactivity issues. Chemical and enzymatic reactions are then used to bind the ammonium cations to the lemon hydrolysate thus creating a structure with cationic character; this increases the affinity that the positively charged protein has for the negatively charged hair shaft and skin cell. The hydrolysate is then cross-linked to increase the refractive index of Quaternized Lemon Shine PF, which further increases the shine benefits it has on the hair shaft.
To increase substantivity to the anionic hair shaft, proteins can also be quaternized. Quaternized proteins contain a quaternary ammonium ion that is covalently attached to the polypeptide chain. Often referred to as quats, quaternary ammonium cations bind to the anionic hair shaft to improve shine and combability while decreasing static and tangles. The chemical structure of the quaternary ammonium group is a central nitrogen atom attached to four alkyl or aryl groups and a halogen (e.g. chlorine).Quaternary ammonium ions are similar to ammonium salts yet they are capable of retaining cationic character in extremely basic environments. As ammonium salts are added to mixtures with a pH above 10, the nitrogen is deprotonated and the salt loses its functional charge.
To further enhance the shine properties, the quaternized proteins can be cross-linked to create an aggregate with increased molecular weight. This allows the formation of a film with a higher refractive index than that of a typical quaternized protein. Additionally, the film formed by the protein may also seal in moisture to prevent desiccation that is often caused by styling tools such as hair dryers and curling/straightening irons.
A half head study was conducted to determine the comparison of a control shampoo vs. 2.0% Quaternized Lemon Shine PF in the control shampoo. Additionally, a comparison between the control conditioner and 2.0% Quaternized Lemon Shine PF in the control conditioner were reported. Each volunteer’s hair was photographed prior to the treatment and again after the shampoo and conditioner had been applied and the hair was styled. The images of the half head study were used in conjunction with a sensory assessment subjectively rating the parameters cleansing, smoothing, dry and wet combability, anti-frizz, overall feel, shine and hydration. This assessment was conducted both before and after treatment. Based on the results obtained, Quaternized Lemon Shine PF is capable of enhancing smoothing, wet combability, anti-frizz, overall feel and hydration when used in a conditioner.
Product may change appearance if exposed to cold temperatures during shipment or storage. If this happens, please gently warm to 45-50°C/115-122°F and mix until normal appearance is restored.
